Open Babel 32-bit Download ##VERIFIED##

Open Babel is available as a binary installer for Windows, both 64-bit (preferred) or 32-bit (indicated by x86 in the filename). It includes several command-line tools as well as a graphical user interface (GUI). The latest version can be download from GitHub.

We discuss, for the first time, Open Babel, an open-source chemical toolbox that speaks the many languages of chemical data. Open Babel version 2.3 interconverts over 110 formats. The need to represent such a wide variety of chemical and molecular data requires a library that implements a wide range of cheminformatics algorithms, from partial charge assignment and aromaticity detection, to bond order perception and canonicalization. We detail the implementation of Open Babel, describe key advances in the 2.3 release, and outline a variety of uses both in terms of software products and scientific research, including applications far beyond simple format interconversion.

Open Babel presents a solution to the proliferation of multiple chemical file formats. In addition, it provides a variety of useful utilities from conformer searching and 2D depiction, to filtering, batch conversion, and substructure and similarity searching. For developers, it can be used as a programming library to handle chemical data in areas such as organic chemistry, drug design, materials science, and computational chemistry. It is freely available under an open-source license from

We outline for the first time, the development and use of the Open Babel project, a full-featured open chemical toolbox, designed to "speak" the many different representations of chemical data. It allows anyone to search, convert, analyze, or store data from molecular modeling, chemistry, solid-state materials, biochemistry, or related areas. It provides both ready-to-use programs as well as a complete, extensible programmer's toolkit for developing cheminformatics software. It can handle reading, writing, and interconverting over 110 chemical file formats, supports filtering and searching molecule files using Daylight SMARTS pattern matching [7] and other methods, and provides extensible fingerprinting and molecular mechanics frameworks. We will discuss the frameworks for file format interconversion, fingerprinting, fast molecular searching, bond perception and atom typing, canonical numbering of molecular structures and fragments, molecular mechanics force fields, and the extensible interfaces provided by the software library to enable further chemistry software development.

Open Babel has its origin in a version of OELib released as open-source software by OpenEye Scientific under the GPL (GNU Public License). In 2001, OpenEye decided to rewrite OELib in-house as the proprietary OEChem library, so the existing code from OELib was spun out into the new Open Babel project. Since 2001, Open Babel has been developed and substantially extended as an international collaborative project using an open-source development model [8]. It has over 160,000 downloads, over 400 citations [9], is used by over 40 software projects [10], and is freely available from the Open Babel website [11].

Open Babel is implemented in standards-compliant C++. This ensures support for a wide variety of C++ compilers (MSVC, GCC, Intel Compiler, MinGW, Clang), operating systems (Windows, Mac OS X, Linux, BSD, Windows/Cygwin) and platforms (32-bit, 64-bit). Since version 2.3, it is compiled using the CMake build system [37, 38]. This is an open-source cross-platform build system with advanced features for dependency analysis. The build system has an associated unit test framework CTest, which allows nightly builds to be compiled and tested automatically with the results collated and displayed on a centralized dashboard [39].

Open Babel is open-source software, which offers end users and third-party developers a range of additional rights not granted by proprietary chemistry software. Open-source software, at its most basic level, grants users the rights to study how their software works, to adapt it for any purpose or otherwise modify it, and to share the software and their modifications with others. In this sense, Open Source functions in similar ways to the processes of open peer review, publication, and citation in science. The rights granted by open source licenses largely coincide with the norms of scientific ethics to enable verifiability, repeatability, and building on previous results and theories.

Beyond these rights, Open Babel (like most other open-source projects) offers open development -- that is, all development occurs in public forums and with public code repositories. This results in greater input from the community as any user can easily submit bug reports or feature suggestions, get involved in discussions on the future direction of Open Babel or even become a developer him/herself. In practice, the number of active contributors has increased over time through this level of open, public development (Figure 3). Moreover, it means that the development of the code is completely transparent and the quality of the software is available for public scrutiny. Indeed, since its inception, over 658 bugs have been submitted to the public tracker and fixed [41].

The Open Babel package is composed of a set of user applications as well as a programming library. The main command line application provided is obabel (a small upgrade on the earlier babel), which facilitates file format conversion, filtering (by SMARTS, title, descriptor value, or property field), 3D or 2D structure generation, conversion of hydrogens from implicit to explicit (and vice versa), and removal of small fragments or of duplicate structures. A number of features are provided to handle multi-molecule file formats (such as SDF or MOL2) and to use or manipulate the information in property fields and molecule titles. Here is an example of using obabel to convert from SDF format to SMILES:

The Open Babel graphical user interface (GUI) provides the same functionality. Figure 6 is a screenshot of the GUI carrying out the same filtering operation described in the obabel example above. The left panel deals with setting up the input file, the right panel handles the output and the central panel is for setting conversion options. Depending on whether a particular option requires a parameter, the available options are displayed either as check boxes or as text entry boxes. These interface elements are generated dynamically directly from the text description and help text provided by each format plugin.

Open Babel has already been referenced over 400 times for various uses. The most common use of Open Babel is through the obabel command line application (or the corresponding graphical user interface) for the interconversion of chemical file formats. Such conversions may also involve the calculation or inference of additional molecular information or application of a filter. Some published examples of these include the following:

I am using Python for making a script to work with some chemical structures in my PhD. I want to install openbabel libraries for python. I tried my best but I could not install it. It always gives error:Error: SWIG failed. Is Open Babel installed?Here is the Python Path on my PC: C:\Users\malih\AppData\Local\Programs\Python\Python36-32. Openbabel is installed at the following path C:\Program Files (x86)\OpenBabel-2.3.1.

pip install is notoriously non-windows friendly. Either go to openbabel website and download + install windows binary, then download + install python binding, or use the unoffical official openbabel python windows build, then cd into the downloaded directory, and perform pip install OPENBABEL_FILE_WINDOWS.whl

However, the wheels already comes bundled with a precompiled obabel, so you really don't need to install the windows binaries version (the one that comes with the setup and all), but you have to know that if you're willing to ship a python script that uses this library, know that it will interfere with systems that do have BABEL_DIR in the environment variables, to fix this you have to include the whole openbabel directory from YourPythonDirectory/lib/site-packages/. in your script's folder.

This page provides 32 and 64-bit Windows binaries of many scientific open-source extension packages for the official CPython distribution of the Python programming language. A few binaries are available for the PyPy distribution.

Open Babel ships a simple converter application called obabel that can be used to trigger the issue described in this advisory. obabel supports -i and -o parameters, which select the input and output formats to perform the conversion. obabel supports multiple input and output files (as does the Open Babel library itself): this technically allows multiple vulnerabilities to trigger in sequence, which in turn could make some vulnerabilities easier to exploit. In this advisory, however, we focus on only one input file and a corresponding output file.

Depending on how the obabel application is invoked, different paths could actually take place. Eventually, pInFormat and pOutFormat (of base class OBFormat) objects are allocated, which are instances of the classes that implement the selected input and output formats.

Wine is a way to run Windows software on Linux, but with no Windows required. Wine is an open-source Windows compatibility layer that can run Windows programs directly on any Linux desktop. Essentially, Wine is trying to re-implement enough of Windows from scratch so that it can run all those Windows applications without actually needing Windows.
